The WhiteHouse.gov petition calling for the extradition of Walter Palmer, the Minnesota dentist who recently admitted to killing Cecil the Lion in Zimbabwe, has surpassed 100,000 signatures, meaning the White House will have to respond to the petition.

“We urge the Secretary Of State John Kerry and the Attorney General Loretta Lynch to fully cooperate with the Zimbabwe authorities and to extradite Walter Palmer promptly at the Zimbabwe government's request,” the petition reads.
